- Kubeadm: add support for certificate chain validation. When using kubeadm in external CA mode, this allows an intermediate CA to be used to sign the certificates. The intermediate CA certificate must be appended to each signed certificate for this to work correctly. ([#97266](https://github.com/kubernetes/kubernetes/pull/97266), [@robbiemcmichael](https://github.com/robbiemcmichael))...

  - `status.conditions` may not contain duplicate types
  - `status.conditions[*].status` is now required
  - `status.certificate` must be PEM-encoded, and contain only CERTIFICATE blocks ([#91685](https://github.com/kubernetes/kubernetes/pull/91685), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Architecture, Auth, CLI and Testing]

- Kubernetes components that accepted X.509 client certificate authentication now read the user UID from a certificate subject name RDN with object ID `1.3.6.1.4.1.57683.2`. An RDN with this object ID had to contain a string value and appear no more than once in the certificate subject. Reading the user UID from this RDN could be disabled by setting the beta feature gate `AllowParsingUserUIDFromCertAuth` to `false`(until...

- When `--rotate-server-certificates` is enabled, kubelet will no longer request a new certificate on startup if the current certificate on disk is satisfactory. ([#69991](https://github.com/kubernetes/kubernetes/pull/69991), [@agunnerson-ibm](https://github.com/agunnerson-ibm))

* Allows extension API server to dynamically discover the requestheader CA certificate when the core API server doesn't use certificate based authentication for it's clients ([#66394](https://github.com/kubernetes/kubernetes/pull/66394), [@rtripat](https://github.com/rtripat))



# v1.11.2

- Fixes an issue where the vsphere cloud provider will not trust a certificate if:
  - The issuer of the certificate is unknown (x509.UnknownAuthorityError)
  - The requested name does not match the set of authorized names (x509.HostnameError)
